YEL206-2F Eccentric Lock Insert Bearing 30mm Bore Double 2F Steel Flinger Seals

YEL206-2F is heavy-duty spherical outer insert bearing equipped with integrated eccentric locking collar, metric 30mm cylindrical bore, both sides extended inner ring design, compatible with standard UCP206, UCT206 and T206 sliding take-up bearing housings for agricultural harvesters, heavy conveyors and outdoor mining equipment. The suffix 2F stands for dual-side steel flinger + multi-lip contact rubber composite sealing structure, far superior dust and splash water isolation performance compared to ordinary DD single rubber seals.

Spherical outer ring delivers ±3° self-aligning compensation to eliminate shaft bending deformation, housing machining tolerance and assembly misalignment. Double-side widened inner ring restricts inner ring deflection on transmission shafts, effectively lowering vibration and running noise under long-term continuous operation. The integrated eccentric cam locking collar forms large contact extrusion force to lock shafts firmly, preventing inner ring slipping for unidirectional rotation machinery. Independent side grease fitting enables periodic supplementary lubrication without complete disassembly of bearing unit. Pre-filled high-viscosity anti-wear lithium grease adapts to harsh working environments full of crop dust, mud and splashing rainwater. All rolling components adopt fully quenched high-purity GCr15 bearing steel with mirror superfinished deep raceway, featuring outstanding impact resistance and long service life. Widely applied to large grain sorting conveyors, heavy feed mixing equipment, heavy lawn mowers, medium quarry belt conveyors and all 30mm metric shaft heavy vibration rotary devices.

Complete metric shaft bearing housing installation drawings, medium-heavy load matching guide and long-cycle heavy dust 2F flinger seal durability test reports can be provided upon customer request.

• Double-side extended inner ring structure limits inner ring tilt on shafts, greatly reduces vibration and running noise during continuous high-speed operation, runs smoother than single-side widened YET series bearings.
• Advanced 2F dual steel flinger composite sealing system: outer steel flinger blocks large mud blocks and crop debris, inner multi-lip rubber seal isolates fine dust and splashing water, specially optimized for severe outdoor farm dusty working conditions.
• Eccentric cam locking design creates large contact area with 30mm metric shaft, reliable anti-slip performance under long-term strong vibration of large grain harvesters and long-distance heavy transport belt conveyors, suitable for fixed unidirectional rotation equipment.
• Spherical outer ring self-aligning function automatically compensates assembly deviation and shaft deflection, reduces extra shaft bending stress and localized abnormal bearing surface peeling wear.
• Independent side relubrication grease nipple supports on-site grease supplement without removing the whole bearing unit, minimizes maintenance downtime during seasonal agricultural production peak periods.
• Fully quenched rolling elements reach HRC60–65 hardness, excellent anti-indentation and contact fatigue resistance, significantly extend service life of frequently impacted heavy conveyor tension rollers.
• Standard universal spherical outer dimension, fully interchangeable with global YEL206-2F series double extended inner ring eccentric lock insert bearings, direct replacement for all standard 206 series bearing housings without structural modification.
• Comprehensive customized service: P6 high precision upgrade, stainless steel anti-corrosion variant, OEM laser marking on outer ring, neutral export carton anti-rust packaging, pre-filled high-temperature heavy-duty lithium grease.
